Marcel Piping CRISL rated manufacturer, supplier & Exporter of ASTM A182 F321 Stainless Steel Flanges, believe in contributing to an enterprises progress, not only as a provider of good services but also as a partner in building a strong business. ASME B16.47 321 Pipe Flange is good choice for applications in the temperature range of up to about 900 °C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion.321H Stainless steel Flange is a modification of 321 steel flange with a higher carbon content, to provide improved high temperature strength.

In Grade 321 Stainless Steel Flange have excellent toughness, even down to cryogenic temperatures. UNS S32100 Flange does not polish well so not recommended for decorative applications. A182 F321/F321H Flange has higher hot strength and particularly suitable for high temperature applications.

We are India’s largest independent stockholder and wholesaler of ASNI B16.5 F321/F321H such as SS DIN 1.4541 Slip On Flanges, Weld Neck Flanges, Stainless Steel ASTM A182 321 Socket Weld Flanges, B16.47 321 Orifice Flanges, ASME B16.48 321 Blind Flanges, A182 F321H Spectacle Blind Flanges, Grade 321 Stainless Steel Threaded Flanges, EN 1092-1 321 Reducing Flanges, SS 321H Ring Type Joint Flanges (RTJ) etc.
